[Devel] Re: [RFC][PATCH] x86_86 support of checkpoint/restart (Re: Checkpoint / Restart)

[Masahiko Takahashi]

Hi Serge,

Thank you for the comment.
I have checked the patch works on the Oren's latest patchset(v13) also.

And, ... I notice the email's subject was incorrect. Oops.
As you know, "x86_64 support" is correct.


Thanks,

Masahiko.
